SLED-KNEE.

Specification of Letters Patent.

Application filed January 28, 1914.

Patented Oct. 20, 1914.

Serial No. 815,021.

To all whom it may concern Be it known that I, Lawrence F. JORDAN, a citizen of the United States, residing at Chattaroy, in the county of Spokane and State. of Washington, have invented new and useful Improvements in Sled-Knees, of which the following is a specification. The present invention relates to sleds, particularly to that class known as bob sleds, such as are used in logging operations for hauling logs, and an object of the invention is to provide a knee for the runners of the sled which will reinforce and strengthen the same without addinggreatly to the weight of the sled, and furthermore to provide a seat for the cross beam of the bunk which will permit of a limited but desirable rocking and longitudinal movement of the bunk with respect to the longitudinal runners of the sled.

Further I propose to construct a knee for sled runners which will embody the desirable features of simplicity, strength and durability and which will dispensewith the employment of start pins and. stirrups.

With the above and other objects in View, the invention resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims. In the drawing: Figure 1 is a perspective view showing the runners and bunk of a bob sled, the runners being provided with my improved means which support the bunk,

Fig. 2 is an enlarged central longitudinal sectional view taken through the device in a line with one of the runners, Fig. 3 is a transverse sectional view on the line 33 of Fig. 2, Fig. 4 is a perspective view of the improvement with the rocker platesremoved, Fig. 5 is a detail perspective view of the rocker plates connected, Fig. 6 is a detail perspective viewof the lower rocker plate, and Fig. Tis a similar perspective view of the upperrocker plate.

Reterring now to the drawing in detail,

the numeral 1 designates the runners of :1:

bob sled, 2 the knees constructed in accordance with my invention and arranged upon the runners and 3 the bunk or cross beam supported upon the knees.

Both of the knees are of a similar con struction, so a detailed description of one may be understood as applying to the second knee. Each of the knees includes a base 4 which comprises a flanged or channeled horizontally to provide ears or member, the sides of the same being spaced. a distance equaling the distance of the runner 1, and the said channel of the base 4 has its upper or connecting plate provided with a plurality of openings 5, all of which. being for the reception of securing elements 13, whereby the plate is retained upon the runner 1. The base comprises a substantially elongated member, so that. the same will engage sufficient lengthof the runner toassist in reinforcing and bracing the said runner. The knee is provided with what I will term a central or transverse brace 7 the said brace including spaced sides 8 and 9 which extend upwardly from their conQ necting web 10, the said web being prouded with an opening whereby the central. brace 7 is secured to the top plate of the base 4. The side 8 is arranged vertically or at a right angle to the web 10, while the side 9 ispreterably inclined from the said web, and both the sides 8 and 9 have their upper portions arranged angularly and horizontally to. provide what I will term ears and which are indicated by the numerals 11 and 12 respectively.

The numeral 13 designates the main brace member for the knee which is arranged longitudinally of the base 4. This member comprises a centrally arched or upwardly curved portion 14, having its ends bent 16, both the said portions 15 and 16 having openings whereby the same will be secured to the upper or connecting member ofthe base 4 The member 13 is of a width sufiicient to be received between the arms 8 and 9 of the central brace 7, and the central portion of the arched member is arranged flush with the horizontally "disposed cars 11 and 12. The member 14 is centrally providedwith an opening and provided with additional openings spaced a suitable distance from the [said opening 15, while the cars 11- and 12 are also provided with openings. The last mentioned openings are adapted for the reception, of securing elements 16, whereby the lower rocker plate 17 is secured to both the central and main brace. The rocker plate preferably has its central portion longitudinally straight, and is inclined or rounded from the said central portion, as shown in the drawings, and the said plate comprises a rectangular member which is of a size to rest snugly upon the ears of the brace 7 and the arched portion 14 arms 15 and of the brace 18. The member 17 has its central portion,v at its transverse edges, formed with extending tongues 18, and is also provided with a centrally arranged elongated slot or opening 19 which registers with the opening 15 in the brace 13.

The numeral 20 dsi 'nates the u 3 er rocker plate for the knee. This rocker plate also comprises a substantially rectangular member, but is fiat, and has its transverse edges centrally notched, as at 21, and the tongues 18 are adapted to be bent within the notches and over the plate 20. The plate 20 is provided with a central downwardly extending stud 22 w iich is received within both of the elongated openings 19 and 15, and the said plate has its corners formed with openings for the receptionof securing elements whereby the bunk 8 is retained upon the knee. The plate 20 is permitted a limited longitudinal movement upon the plate 17 as well as a limited rocking movement upon the said plate, and t'rom the above description, taken in connection with the accompanying drawing, the simplicity of the device as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detaileddescription.

Having thus described the invention, what I claim is:

1. A knee for sled runners including a channeled base adapted to engage with the sides'ot' the runner and rest upon the top of the same, a main brace arranged longitudinally of the-base, a transverse brace ar-' ranged centrally of the base and main brace, a plate secured to the braces, and a bunk supporting the rocker plate loosely connected with the first mentioned plate.

2. A knee for sled runners including an elongated channeled base which is adapted to be arranged upon the runner to engage with the top and sides thereof, an arched main brace arranged longitudinally of the base, an inverted substantially U-shaped brace arranged transversely of the runner and positioned centrally of the main brace, a plate secured to the braces, said plate being substantially curved in cross section, a fiat rocker plate loosely connected with the said round plate, and the said fiat plate adapted to support the bunk upon the sled.

3. A knee fo sled runners including a gularly of the runner, both plate arranged upon the :rocker plate having its supporting channeled base, a main brace comprising an arched member arranged longitudinally of the base, a transverse brace arranged centrally or the longitudinal brace, said transverse brace including a substantially U- shaped member, one of the side arms of which being arranged at a right angle to the runner, the second arm being arranged anof the arms having their ends outturned to provide ears, a rocker plate having a central straight portion and being rounded to its longitudinal edges from its said straight portion secured to the ears and to the arched longitudinal brace, and a bunk supporting rocker plate loosely connected with the first mentioned rocker plate.

at. A knee for sled runners including a channeled base, an arched main brace arranged longitudinally of the base, a transverse brace arranged centrally of the runner and of the main brace, an arched rocker plate secured to the braces, said plate having its transverse ends formed with bend able fingers, a fiat bunk supporting rocker arched plate, said ends notched, and the fingers of the first mentioned plate 1 adapted to be bent to within the notches of the bunk supporting rocker plate.

5. A knee for sled runners including a channeled base, a main brace arranged longitudinally of the base, a transverse plate arranged centrally of the base and main brace, an arched plate disposed transversely of the base and connected with the braces, said plate having a certral elongated opensaid plate having its transverse edges. flat bunk rocker plate, said plate being centrally provided with a stud which is adapted to be received within the slot of the first mentioned plate, said rocker plate having its transverse edges centrally notched, and the said notches adapted to receive the fingers of the first mentioned plate when the said fingers are bent over the rocker plate.

In testimony whereof I afiix my signature in presence of two witnesses.
